Application filed May 20, 1911. Serial No. 628,585. i

To all whom it may concern:

Fairhaven, in the county of Bristol and.

State of Massachusetts, have invent-ed certain new and usefulImprovements in Nail- Gapping Machines, of which the following is aspecification.

In the manufacture of nails to be used for upholstering or for otherpurposes which require an ornamental nail, it is customary to make upeach nail from a number of parts including an ornamental cap, a shank,and a third member by which the cap is attached to the shank. When a.nail is made up in this manner a standard shank member of iron orothermetal may be used and the cap may be made of sheet brass, copper,'orother metal, plain or embossed or otherwise em bellished. I i

The object of the present invention is to provide amachine adapted toassemble the several component parts of a nail of the character abovedescribed. The assembling operation as carried out by the m achinehereinafter described consists in assembling a shank member, a cap. anda filling piece The machine also comprises ejector mechanism by whicheach finished nail is ejected from the forming dies.

The machine also includes various mechanisms, hereinafter described indetail. whereby the operations of assembling and forming the variousparts of the nail are rendered automatic so that an indefinite number offinished nails may be produced so long as the supply of parts is notexhaust-ed.

The term nail as used throughout this specification and the appendedclaims is used solely for the purpose of description and not forlimitation. Analogous fastening devices, such, for example, as rivets ortacks, may be provided with caps in the same manner as that by which thecaps are attached to nails.

The details of mechanism hereinafter described need only be varied inproportion,

butnot in operation, in order to adapt the machine to produce compositetubular rivets or other similar fastening devices instead of thecomposite nail illustrated and described.

Of the accompanying drawings which illustrate one form in which'theinvention may be embodied: Figure 1 represents a front elevation. Fig. 2represents a top plan I view of the machine. Fig. 3 represents avertical section of the mechanism for ejecting the finished nails. Fig.4 represents a side elevation of the machine. Fig. 5 represents anelevation of a slide'for supporting one of the raceways, and actuatingmecha-' nism therefor. Fig. 6 represents a topplan view of a carrier forthe nail caps. F 7 represents a horizontal section of the means fortransferring a nail from its raceway to the assembling dies. Fig. 8represents a view similar to Fig. 7, showing the devices in a differentposition. Fig. 9 represents a top plan view of the three raceways forthe caps, linings and nails respectively, and the means for transferringa cap and a nail into position where they are assembled. Fig. 10represents a front elevation, partly insection, of the mechanism shownby Fig. 9. Fig. 11 represents a front elevation of the mechanism shownby Fig. 9, in a different position. Fig. 12 represents a front elevationof the cap-transferring device in position to be retracted from theassembling die. Flg. 13 represents a front elevation, partly in section,of the assembling dies with the several parts of a nail in partlyassembled relation. Fig. 14 represents an elevation,

partly in section, in a plane from front 'to large cap for the nail isindicated at :0 and a. lining is indicated at w. The lining is in theform of a washer, and consists in a disk having a central openingthrough which the shank of the nailis inserted. The rim of I the cap isswaged about the rim of the lining 7 so that the head w'is positivelyconfined between the cap and the lining.

Before describing in detail the mechanism of the machine for. assemblingthe nail as shown by Fig. 16, the machine and its operation may begenerally stated as follows:

-The caps are supplied from a hopper by a by a suitable hopper, fromwhich they are.

conducted by a third inclined raceway. The raceway for the linings ismovable, and it is reciprocated at the appropriate intervals, as will behereinafter explained.

The caps are transferred one by one from the lower end of their racewayinto position between two coeperative assembling dies. The nails arelikewise transferred from the lower end of their raceway into positionin alinement with the assembling dies. The raceway containing thelinings is moved to place the foremost lining'in position to receive thenail in alinement with the assembling dies; and while the componentparts of the nail are all held in alinement with the dies the dies arebrought together in such fashion as to insert the point of the nailthrough the lining, place the cap upon the head of the nail, to insertthe point of the nail into the lower die, to pause long enough to givethe cap transferring device suflicient time to recede out of the path ofthe'dies, to move toward each 1 through which the bolts extend.

other so as to complete the assembling of the nail, cap and lining, andto swage the cap around the edge of the lining, after which automaticejection of the assembled nail is effected.

The raceway for the nails :0 is indicated at20, the raceway for the caps41: is indicated at 21, and the raceway for the linings w is indicatedat 22. The raceways 20 and 21 are fixed to the frame of the machine, butthe raceway 22 is movable horizontally so that its lower end may moveinto alinement with the assembling dies and recede therefrom. Thevarious mechanisms hereinafter described are all mounted in a frame 23mounted on a base 24. The hoppers for the nails, caps and linings areomitted. The raceway 20 is aflixed to a bracket 25 which is adjustablysecured to the frame of the machine by bolts indicated at 26, thebracket being provided with vertical slots 27 The bracket is providedwith a setscrew 28 which is arranged to rest upon an upper surface ofthe frame to determine the vertical position of the bracket and thevarious devices supported thereby.

' The raceway 21 is afiixed to a separate bracket which "is indicated'at 29. The bracket 29is located on the op osite side of the center ofthe machine wit the bracket 25, and is attached to the frame in the samemanner as the bracket 25. The bracket29 is likewise provided with asetscrew, which is indicated at 30, by which its'vertical position maybe determined.

. The assembling dies are indicated at 31 and 32, the die 31 beingarranged above the die 32 in vertical alinement therewith. The die 31 isaffixed in the lower end of a plunger 33 which is movable in a bearing34 on the frame. The upper end of the plunger is connected by a link35'with an lever 36 whose rear end is connected with an adjustableconnecting rod 37. The oprelation to operating 38. The frame 23 isprovided with holes a which register with the holes in the oper atinglever so that the fulcrum pin 38 may be transferred from one position toanother in order to vary the throw of the operating lever. The lower endof the connecting rod 37 is in the form of a fork and straddles the mainpower shaft 40. A cam roll 41 on the connecting rod 37 is arranged toengage an operating cam 42 on the shaft 40, and is held in contact withthe cam by a'spring 43, one end of which is connected to the lever '36and the other end of which is connected to the frame.

According to this embodiment of the in vention, the lower die 32 is notmoved for the purpose of cooperating with the upper die, but it ismounted so as to be movable to and from alinement with the upper die forthe purpose of ejecting the finished nail. As shown by Fig. 3, the die32 is seated in a socket formed in a holder 44. The holder is mountedupon a stud 45 whose ends are mounted in, bearings 46 afforded byportions of the frame work. The holder 44 is connected by a link 47 witha lever 48 mounted upon a fulcrum pin 49 and pro' vided with a roll 50cooperating with a cam 51 on the shaft 40. A spring 52 connected to thelever 48 serves to keep the roll 50 against the cam 51 and to move thedie from the position indicated by solid lines to the position indicatedby dotted lines. An adjustable stop 8 is adapted to beengaged by the dieholder 44 so as to position the die in alinement with the upper die 31,

' and an eccentric stud 53 is provided for conthe lever 48 is split andis provided with a clamping screw 54; The cam 51 '1s so formed as tohold the die 32 in alinement with the die 31' throughout the assemblingand swaging operations, and to release the die so that it may tiltforward after 'the swaging operation has been performed. When thediemoves to the dotted line position, an ejecting device, hereinafterdescribed, acts upon the nail to eject it from the die. 1

The raceway 22 by which theliningw? are conducted to the assemblingdiesis affixed to a slide 55. See Figs. 4 and 5.) The slide is mounted inguides 56 on the frame 23 in which it is moved from front to rear by anoperating lever 57. The lever is mounted upona fulcrum pin 58 and is.provided with a roll 59 which cooperates with a cam 60 on the shaft 40.The connection between the operating lever and the slide comprises aneccentric stud 61 clamped in the end of the operating lever which issplit and which is providedwith a clamping screw 62. A square block 63is mounted upon the inner end of the stud 61 and occupies a verticalslot 64 formed in the'slide. By turning the eccentric stud 61 in onedirection or the other, the slide may be adjusted forward or backwardwith relation to the operating lever. A- spring 65 acting upon theoperating lever exerts its tension tomove the slide forward and keep theroll 59 in engagement with the cam.

The nails 00 are transferred one by one from the lower end of theraceway 20 into alinement with the assembling dies by a reciprocatorycarrier 66 having coacting gripping fingers 67 and 68.. The finger 68 ismovable with relation to the finger 67 and is connected therewith by apivot pin 69. A spring 70 acting against a rear extension 71 of themovable finger tends to close the fingers in gripping position, but thefingers are positively opened to receive a nail by an abutment 72 whichis arranged to be engaged by the extension 71 when the carrieris'r'etracted to nail-receiving position. The carrier 66 is aifixed to aslide 73. (See Figs. 1, 4 and 7). The slide is mounted at the lower endof the bracket 25 between horizontal gibs 74, and is connected, ashereinafter explained, with an operating lever 75.

The lever is adjustably secured upon a rock shaft 76 mounted in suitablebearings in the frame, and is provided with an arm 77 at its rear end onwhich is mounted a roll 78 which cooperates with a grooved cam 79 on theshaft 40. (See Fig. 2). The cam operates the lever positively in bothdirections, but the lever is connected with the slide 73 in such mannerthat the transferring movement of the slide will be yielding. For thispurpose the slide is provided with an extension rod 80 which" isconnected with a in 81 on the lever by a helical spring82. he slide 73isprovided with an abutment 83 against.

which the upper end of the lever 75 is held by the spring. When theoperating lever is moved to transfer a nail from theraceway to theassembling dies, the force of the lever is transmitted to the slidethrough the spring 82; but when the operating lever is moved in theopposite direction it acts positively u on the slide through the mediumof the a utment 83. The purpose in providing the springconnection'between the lever and the slide is to avoid breaking themechanismin case a nail becomes dislodged so as to impede themovement ofthe carrier when the operating lever is moved. a

The nails are prevented from dropping out of the lower end of theraceway by a pivoted check finger 84 which is normally eld closed by.spring 85. (See Figs. 9 and 10). The upper surface of the check fingeris in the horizontal plane of the upper surface of the race, so that thehead of the foremost nail may rest upon the check finger.

to permit the nail to move-laterally from the lower end of the racewaywhen the gripping fingers are moved to transfer the nail to theassembling dies. The carrier is provided with a stop member 86 which isarranged to engagethe shank of the nail near its point for the purposeof preventing the point from swinging forward when the upper end of theshank is arrested by the check finger 84. When the nail carrier is movedto the left from the position shown by Figs. 7 and 9, the movable gripfinger 68 is released by the abutment 72 so that it may close upon theshank of the nail by reason of the tension of the spring 70.' The closedposition of the grip fingers is shown by Fig. 8. As the carriercontinues to move toward the assembling dies, the forward end of thefinger 67 passes in front of the shank of the second nall in the racewayand in this way prevents the descent of the remaining nails in thera'ceway until it is again retracted to the position shown by Figs. 7and 9. The abutment 86 which is aflixed to the nail carrier keeps thepoint of the nail in the desired transverse vertical plane while thenail is being carried to the assembling dies, so that the point of thenail may be. more readilv alined with the center of the lower die. Thelateral position of the point of the nail is' determined by a deviceattached to the raceway '22. as hereinafter explained.

While the nail-gripping fingers are in the act of carryin a nail to theassembling dies, other mechanism is operated to transfer a cap m fromthe raceway 21 into alinement with the assembling dies. The caps aretransferred by a carrier 87 which is afiixed to a slide 88. The slide ismounted between -90 The check finger is so arranged as to openhorizontal guides 89 at the lower end of the bracket 29, as. shown byFig. 1. The slide 88 is operated by mechanism like that described upperend of the lever is held by the spring:

against an .abutment 98 on the slide:

When the foremost cap in the raceway is released, as hereinafterexplained, it slides upon the cap-receiving surface 99 of the carrier.(See Fig. 6). Ashoulder 100 limits the forward movement of the cap andprevents it from sliding off the carrier. The carrier is formed with arecess 101 for the reception of a cap-gripping finger which is mountedupon the upper die 31 as hereinafter explained. The cap is held in thedesired position on the carrier 87 by a spring latch 102 which ismounted upon a fulcrum pm 103. A rear extension 104 of the latch isengaged by a spring 105 which normally holds the cap-engaging portion ofthe latch in operative position, as shown by Figs. 1, 10 and.11.. Therear face of the carrier is parallel to ,the direction in which thecarrier moves and is arranged in engagement with the forward end of theraceway 21. The carrier, having a cap thereon, as shown by Fig. 9, ismoved to the right, thereby closing the forward end of the raceway andholding back the caps. remaining therein. When the carrier has beenmoved into alinement with the assembling dies, as shown by Fig. 11, itremains statlonary for a brief period during which the cap thereon isgrasped by a pair of coacting fingers 106 mounted upon the die 31.Duringthis momentary pause of the carrier, the die 31 and fingers 106descend until the finger at. the left occupies the recess 101 in .thecarrier and the finger at the right has engaged the latch 102anddepressed the free end thereof to the horizontal plane of the loweredge of the cap. When the die 31 and fingers 106 have descended to thispoint they remain stationary for a brief period during which the capcarrier is returned tocap-receiving position. When the free end of thelatch 102 is depressed by, the right-hand finger 106, the extension 104of the latch is engaged by a spring-actuated retaining pawl 107pivotally mounted upon the carrier. The retaining pawl serves to keepthe latch in its retracted position while thecarrier is moving back tocap receiving position, but the pawl is automatically operated torelease the latch when the carrier has returned to capreceivingposition. For this purpose the pawl is provided with a finger 108, andthe bracket 29 is )provided with an abutment 109 arranged in t e path ofthe finger 108. The finger strikes the abutment just before the carrierreaches the limit of its return move- .ment, so that the latch 102 mayresume its cap-engaging position before the next cap moves upon thecarrier. r

The cap-sup orting mounted direct y upon the die 31 but they are mountedupon a bushing 110 which is adapted to slide up and down upon the die. Afriction device (see Fig.- 14) comprising a plug 111, spring 112 andscrew 113, is inserted in the bushing 110 so as to act upon the shank ofthe die to support the bushin at whatsoever position it maybe withrelation to the die. The friction device is 1nserted in a boss 114projecting laterally from the bushing. This boss is adapted to engage anabutment 115 adjustably secured to the plunger guide 34, as shown byFigs. 1 and 4. The bushing is provided with a second boss, indicated at116. This boss is adapted to engage an adjustable abutment 117 in theform of a setscrew, as shown by Figs. 4 and 14. The abutment 115 isarranged to engage the lower side of the boss 114 while the abutment 117is arranged to engage the upper side of the boss'116, sufiicientdistance being provided between the two abutments to enable the bushing110 to move for a considerable distance with the die without engagingeither of its abutments. The cap-supporting fingers 106 are mounted inthe bushing 110 by means of fulcrum pins 118, and their upper ends areengaged by springs 119 by which they are normally closed. The lower endof the die 31 is frus'to-conical, as indicated at 120, and the lowerends of the fingers 106 are bent inwardly at an angle conformingsubstantially to the angle of the portion 120. When the plunger 33 israised to elevate the die 31, the boss 116 engages the abutment 117,thus causing the bushing 110 to occupy the relation shown by Figs. 1,11, 13 and 14. WVhen the bushing is in this position the lower ends ofthe fingers 106 are closed by their fingers 106 are. not

springs as far as the diameter of the die 31 will permit. The actualdistance between the extremities'of the fingers is slightly less thanthe diameter of a cap at. When the plunger 33 is depressed to carry thedie to the position shown by Fig. 12, the fingers 106 are forced apartby the cap which they grip with spring tension. Upoii retraction of thehorizontally movable cap carrier, the cap-is left supported by thefingers 106, as shown by Fig. 13. When the plunger 33 is furtherdepressed to eflect the swagin of the cap, as hereinafter explained, theoss 114- on the bushing 110 engages the abutment 115, and continuedmovement of the die 31 spreads the lower ends of the fingers 106 asshown by Fig. 15. The fingers remain spread in this manner until theboss 116 of the bushing is once more moved into engagement with theabutment 117.

The linings are prevented from passing freely out of the lower end ofthe raceway 22 by a pair of spring-closed fingers 121. These fingers arepivotally mounted upon the raceway by pivot studs 122 and are normallyclosed against stop pins 123 by springs 124. Affixed to the upper sideof the raceway is a plate 125 in the forward edge of which is a V-notch127 whose function is to position the point of the nail held by thetransferring fingers 67, 68. The raceway 22 occupies the position shownby solid lines in Fig. 9, while the carriers 66 and 87 are moved towardeach other to place a nail and a cap in alinement with 'the assemblingdies. While the carrier 66 remains stationary for a brief period,supporting a nail between the assemblin dies, the raceway 22 is movedforward to t e position indicated by dotted lines in Fig. 9, by whichmovement the plate 125, having the notch, engages the shank of the nailnear its point, as shown by Fig. 11, thereby moving the point of thenail laterally along the rear face of the abutment 86 to a position inalinement with the center of the assembling dies. There is a briefperiod of time when a cap, a nail and a linin are held in alinement witheach other, as s own by Fig. 11. The die 31 in moving toward the die 32after the retraction of the carrier 87, places the cap su ported by thefingers 106 upon the head 0- the nail as shown by Fig. 13 and forces thenail downwardly between its supporting fingers 67, 68, until "the pointof the nail is inserted in a central bore 128 in the lower die, asshownby Fig. 13. The point of the nail, before passing into the bore128, passes through the central hole in the lining m When the die 31 hasdescended to the position shown by Fig. 13, it remains stationary for aninstant while the nail carrier is retracted out of its path. The nail,during this retractory movement of its carrier, is extracted from thefingers 67, 68, and is then free to drop until the point thereof engagesa spring plunger 129 in the bore of the lower die. A collar 131 isformed upon, or otherwise secured upon, the plunger 129 so as to form ashoulder against which the spring 130 may act to elevate the plunger.The raceway 22 is then retracted out of the path of the upper die to theposition shown in Fig. 9 by solid lines, and the die descends to theposition shown by Fig. 15, thus depressing the plunger 129 and swagingthe rim of the cap. The upper die is then raised, but the spring plunger129 in the lower die is held 1n its depressed position by a spring latchshown by Figs. 3 and 14. The plunger 129 extends through the fulcrumstud 45 and projects below the bottom of the die holder 44, and it isnotched to form a shoulder 132. Attached to the base 24 isalatch133=which is engaged by a spring 134 and which is adapted toautomatically engage the shoulder 132 as shown in-dotted lines by Fig.14. After the upper die has been raised, the cam 51 effects a rockingmovement of'the die holder 44 to the position indicated by dotted linesin Fig. 3, thus moving the lower end of the plunger 129 laterally away'from the latch 133. In this way the plunger is released from the latchand is forced upwardly by its spring 130 so as to eject the finishednail. At the time of ejecting the nail the die is inclined from itsvertical line, and the nail at such time is ejected away from themachine, so that it may be deposited in a suitable receptacle. When thedie holder 44 is rocked back to its vertical position, the plunger 129is again placed in alinement with the latch 133 so that at thecompletion of the next swaging operation the shoulder 132 will once morebe engaged with the latch. 133.
